I have 2 beryl setup. One running wireguard server connected to my cox router. i have port forwarding rules setup on router.
The second beryl is connected to router wifi. I am trying to run wireguard client on it and it never starts. Here is the log :

What am i doing wrong ?

Mostly it could be an issue that both network segments are the same (so both 192.168.8.x) for example. But please have a look into this guide How to troubleshoot WireGuard to check all stuff that might be the issue here.

@admon how do i go abt changing the assigned IP for the travel router ?

4

If it is like this (please check before!) you will need to change the LAN network range by changing the IP of the router from 192.168.8.1 to something different like 192.168.18.1 for example.

See LAN - GL.iNet Router Docs 4

@admon i updated the travel router to 192.168.18.1. Do i have to change the DHCP range ?

Should adjust automatically.
Reboot the router, just in case, so all devices will get new addresses.

@admon still doesnt start

Did you check all other things from my linked post above?

90% of the the problem is the server side.
Pls check your public IP and port foward.

But pls test the vpn client router in another network, not the same as the server.

You can also test a wireguard config on your phone, while putting your phone to cellular data, not wifi.
